The ACE (Automatic Content Extraction) evaluations run by NIST from
2000 to 2009 define a quite general set of information extraction
tasks, including entities, (binary) relations, and events.  Jet
provides full support for these tasks using a set of corpus-trained
extraction components.  This includes the </font><a href="ACE.html"><big><font

extraction task, and a variety of support utilties for training and
scoring individual components.  These utilities are invoked by<br>
